PIN-FASTENING DEVICE.

Application med Tune ao, 1927. serial No. 202,568,

The present invention relates to a pin having a head plate and has as one of its objects the provision of a durable and cheap structure of the type mentioned.

A second object of the invention is to provide a head structure well adapted for a double pronged pin and capable of rapid manufacture.

Another object of the invention is to provide a rapid and cheap method of manufacturing pins having rigid head plates.

With these and, other objects in view the invention consists of certain novel features of construction and of operation as will be more fully described and particularly pointed out in the appended claims. h

It has been known to Vmake a pronged pin of a single piece of wire bent into a shape permitting the attachment of a cap or head thereto. `Such ins, however, have required expensive mac inery for their manufacture. The ordinary headed straight pins, such as bank pins, however, are manufactured in enormous quantities 'and can be bought very cheaply in large lots.

In the drawing7 I have illustrated a pin v according to the present invention and having a relatively large head, and which is made from one or more pins of ordinary type and a specialhead structure.

Referring to the drawing, 20 indicates a head plate to which one or more pins is to be secured. The plate 20 may be made rigid if. desired sufiiciently to stand the stress it is expected to encounter in use. Preferably the pins connected to the plate 2O are of the ordinary type having a pointed shank 22 and a small round head 24. In the device illustrated in Figures 1, 2 and 4 two pins 22 are attached to the plate 20. In

the embodiment illustrated in Figures ,1, 2, 4, 5 and 6, plate 20 is notched to provide two pairs of aligned slots 26, 26 and 28,128, respectively. A pin is secured to .plate 20 by inserting its head 24into a slot 26, then bending the pin in a plane perpendicular to the plane of the plate so that the portion 30 of the shank lies parallel to and 1n contact with one Aface of plate 20 and overlies the other slot 26. The pin 22vis then bent again so that a. curve `or bent portion 32 lies in the other slot 26, the part 30 being short enough to prevent head24 or bend 32 from slipping out of theV end of its slot 26. Preferablmalso, the pin is bent sufficiently so thatthe remainder of the shank 220i Y theL pinalso lies approximately parallel to the plate 20. The operation just. described is then repeated. if desired, `with respect to another pin and the `slots 28, 28 so as to attach the second pin 22 to the plate` 20 or both pins may be thus positioned simultaneously, if desired. After one or more pins has or have been secured to the plate 20, it is preferred to secure a cap 34 to the plate. The cap may be secured to the plate 2() in any convenient manner but preferably this is done by rolling or crimping the margin. of one member over that of the other. In the arrangement illustrated in Figures 1 and 2 cap 84 is `first struck up from a blank into the form of a round cup having a cylindrical flange, the plate 2() is then inserte( therein and secured thereto by rolling inwardly the edge of the ange so that the cap 554 embraces the edge of the plate 20, as illustrated in Figure 4. It will be seen that the cap 34 lies close to the portion 30 and pins 22 so that the pins 22 are prevented from sub- 'stantial'movement 'perpendicular to plate 20 and are'held in their interlocking enagement lwith plate 2O irrespective of the eads 24 of the pins. It Will be seen, therefore, that While the use of headed pins is convenient, the present invent-ion is not limitedto headed pins. Moreover, if the portion 30 of the pins is long enough to let the pins slip out of slots 26 or 28, the cap 34, or the like, acts to prevent the pins leaving the ends of the slots either at the =head 24 or at the bend 32. In Figures 9 and 10 is illustrated in modified form a head-plate 20a. Plate 20 has an apertured segment 38. Segment 38 is bent substantially at rightangles to the body of the plate 20aand is apertured as illustrated at 40. Two or more of the apertures 40 may be made in the 'flange or segment 38, one of which appears in Figure 10. The apertures 40 are each in alignment with one of the slots A26, 28 in the opposite edge of the plate 20a.

In securing pins to plate 20 a pin is run through one of the apertures 40 Withits head towards the outside of the segment 38 of the plate, the shank 22 of the. pin extending along the plate 20' and the pin is then bent around the plate to bring the curved-neck or bend 32 Within the slot 26 or the like in the opposite edge of the plate and preferably so the shank 22 lies approximately Aparallel to plate 20a. It will be evident thatthe pins have interlocking engagement with the plate 20.

In Figures 11 and 12. I have illustrated ,still another formof head-plate 20". Platel 2()b4 isformed by making a cut inthe plate to define a segment 38a and then bending the segment 38 at right angles to the body of theplate. By cutting plate 20" parallel to its outer circumference asjust described,

segmentBSacan be positioned as illustrated in Figure 12 so that it extends outwardly into the cap at the centre of the cap and where there is themost room between the cap and the plate to receive the segment.

Segment 38aL has apertures 40a therein in alignment with the slots 26 and 28 in the outer edge of plate 20". A pin may be secured to the plate 20b by the same method as'previously describedin connection with the attachment of pins to plate 20a.

It has been known to provide double pronged pins With means such as snap fasteners of the type used on gloves for releasably attaching articles to the pins. In

Figures 13 and 14 is illustrated a double pin according to the present invention provided with a cap arranged to act as a socket member of a glove type fastener. In Figures 14 and 15, I have illustrated a cap 34, the center of which isl punched inwardly to provide a segmental opening 42. The edges of this opening 42 are bent inwardly, as illustrated at'44 and are also cutvalong radial lines. as illustrated at 46. By the arrangement just described'the'cap 34" is adapted to releasably retain the'boss or head of a glove t e fastener stud,the edges vof opening 42 eing adapted to spring to one side to admit the head ofthe stud and to contract again after it has Vbeen forced through the opening 42. Ca 34" is illustrated in connection with the ead plate'-20 but may be used with any kind of'head plate desired. Cap 34h has a attened-front face to facilitate its use as a part of'a snap fastener and as illustrated is provided with a ldistinct groove '48 just within rits outer edge forming a socket for-the edge iofthe plate 20a. However, the vvusefof tlief-'groove 48 is a matter of choice.

In 1`igures15v and 16, I have illustrated a pin having a cap piece orfrnembe'r 34. The pin illustrated inFigures 15 and 16 is also designed for use as a part of a snap fastener, the cap member 34c having a' central opening -42a to permit the insertion of the stud member ofthe `snap fastener.

Cap 34C, howe'ver,'is deepenough Vto provide room between the plate 20 and the inner face of the cap for a' socket member 50 of the type ordinarily used in snap fasteners. The cap 34c is'similar to cap 341 in that it has a distinct shoulder and a flange on its edgeformin'ga groove 48 for receiving the edge of the head plate 20, or the like.

' I have-herein shown and described the 'end 'of the pin stems as being upset to form a head but the head may be formed inlany desired Way to perform the function ofthe upset portion.

The foregoing description is directedy sole- Y ly towardsthe constructions illustrated but I desire it to'be understood thatI'reserve the privilege of resort-ing to all the mechanical chan es to which-'the device` 'is susceptible, the invention beingv defined' and limited only'by the terms of the appended claims.

I claim: v

1. The combination of-fa. head plate having alinged openings in its edge, a pin hav- Y in va portion extending across the face of sald plate and having a portion bent to lie in one of said openings, and a cap member fixed to said plate 1n position to prevent material movement of said pins in a direction perpendicular Ato said plate.
